4 Design Features Design Features VLAN VLAN is short for Virtual Local Area Network, and is generally dened as a broadcast domain. It can be viewed as a group of end nodes which can communicate with each other even though they may be located on different physical network segments. The Fast EtheRx switch provides a simple solution to protect your network against broadcast storming by creating segments based on Layer 2 Ethernet information.
Design Features 5 Full-Duplex Full-Duplex transmission means that dedicated inbound and outbound channels are established for bi-directional transmission of data. This allows the collision detection mechanism (CSMA/CD) to be by-passed, thus decreasing transmission delay normally caused by listening, collisions, and packet resends when operating in half-duplex mode.
6 Hardware Installation Hardware Installation Before you begin installing network cables, please take a few moments to familiarize yourself with Fast EtheRx Switch. The functions on the front and rear panels are illustrated in the following sections.
Hardware Installation 7 Full Duplex and Collision LED The FDX/COLL LED uses a single color LED to display two functions. A solid green light indicates that Full-Duplex operation has been detected. A ashing amber light indicates that a collision has occurred in half-duplex mode. FullDuplex mode is auto-negotiated on all UTP ports. Fiber FX module port (optional) The ber FX module port can be used with an optional MT-RJ, ST, or SC ber module. Port 1 & 2 on the switch are associated with this module.
8 Software Installation Software Installation The Fast EtheRx Switch has several advanced features which can be congured from a Windows 95, 98, NT or 2000 workstation using the provided conguration cable. The software utility allows for VLAN, link trunking, broadcast storm control, secure mode trafc ltering and ow control conguration. The switch conguration software can only be installed on a Windows 95, 98, NT or 2000 system. To install the software, follow the directions below: 1.
Kingston Switch Configuration Utility 9 Use this option to open a previously saved conguration le. Save the current conguration to a switch conguration le. Save the current conguration with another le name. Device Type Choose the type of device that is connected for conguration. There are six types which can be selected, the 16, 24 and 32 port models, with or without the ber option. Use the properties button to begin configuration settings.
10 Kingston Switch Configuration Utility Use this button to save the current conguration data to the device. After a successful write operation, the device automatically resets and initializes the new conguration. If the write operation fails, check the following: • Verify the conguration cable is well connected. • Ensure that the conguration cable is connected directly from the PC to the Switch.
Kingston Switch Configuration Utility 11 Device Conguration Properties System Parameters adjusted in this window will control overall system performance. SuperMAC • Enable: When a collision occurs, the port on which the collision occurs will perform a more aggressive back off algorithm of up to 3 slots. • Disable: This is the default setting, when a collision occurs, the device will perform the IEEE802.3 standard exponential backoff algorithm.
12 Kingston Switch Configuration Utility Aging Time The address-aging timer is built in to the table aging process. The minimum time is 1 second and the maximum is 510 seconds. 255 is the default value, if the number exceeds 255 it must be an even number. Broadcast Storm Control Threshold The Broadcast storm control function limits the number of consecutive broadast packets for each port that has Broadcast Storm Control enabled.
Kingston Switch Configuration Utility 13 Port Individual port parameters are congured from this window. Select the port from the window on the left hand side and then modify the parameters on the right. Use the Apply to Other Ports button to assign the same setting to other ports. Port Selection Designates the port to be congured. Security • Enable: Packets which result in security violations at the designated port will be discarded.
14 Kingston Switch Configuration Utility Address Learning • Enable: This option is enabled by default, which will cause the MAC address of the source of a packet to be learned. • Disable: When disabled, the MAC address of the source of a packet from this port will not be learned.
Kingston Switch Configuration Utility 15 Trunk Assignment The Kingston KNS1650R, KNS2450R, and KNS3250R switches support link aggregation/trunking. Trunking is a method of grouping multiple physical links as a single logical link. The benet is to be able to group multiple lower speed links into one high speed link for bandwidth aggregation. For instance, four full duplex 100Mbps links, such as port 1-4, could be grouped into one 800Mbps link for Trunk 1.
16 Kingston Switch Configuration Utility Load Balancing Method In a multiple link trunk, the links within a trunk should have an equal amount of trafc in order to achieve maximum efciency. Thus, some sort of load balancing amongst the links of a trunk must be deployed. The Kingston KNS1650/R, 2450/R, and 3250/R switches support MAC address based and port based balancing methods. Using these methods, any packet with a trunk destination received by the switch can be forwarded to a proper trunk port.
Kingston Switch Configuration Utility 17 Sample source MAC address Sample destination MAC address 00:C0:F0:1C:23:48 00:C0:F0:22:32:51 Last Byte The byte is in hexadecimal format, the chart below shows the binary value and the bit numbers: Byte = Bit Data Bit Number: 76543210 Last byte of source MAC address (SA) 48 01001000 Last byte of destination MAC address (DA) 51 01010001 The mapping rule is described below: 1.
18 Kingston Switch Configuration Utility Load Balancing Mapping – Port Based The port-based load balancing method is an explicit port assignment scheme. It requires that all other ports are assigned to a specic link (trunk port) in the trunk. When the switch receives a packet with a trunk destination, it will automatically forward the packet to a trunk port based on the port it came from.
Kingston Switch Configuration Utility 19 VLAN This window allows users to dene VLAN membership by groups of device ports. Any individual port or trunk can be a member of a VLAN group. A VLAN group is basically a broadcast domain, but any port/trunk is not limited to belonging to only one VLAN group. The forwarding rule is that packets from the source port/trunk will only be forwarded to a destination port/trunk within the same VLAN group.
20 Disable: Kingston Switch Configuration Utility This option is selected by default. Packets received with an unknown unicast destination address (DA) will be forwarded to all ports (except the receiving port) within the same VLAN groups that the received port (trunk) belongs to. Flood control is available only when at least one VLAN group is assigned. And the out-link port must be assigned when ood control is enabled for proper operation.
Kingston Switch Configuration Utility 21 The group count is not limited. Users can specify n VLAN groups or even more groups for any n (n=number of ports on your switch) port switch. But note that after writing to the device, only the information of the rst n/2 added VLAN groups can be read back from the device of n port switch. Note: Once at least one VLAN group has been added, the system will automatically gather all un-selected members as an implicit VLAN group.
22 Kingston Switch Configuration Utility Explicit Address Table Page The address table of the switch uses address learning (dynamic) or manual entry (static). Static entries are added to the address table of the device in this window. Static address entries are not aged or updated by the switch’s address learning. Explicit Address Table The list box displays all explicit (static) entries for the address table. Each row is an entry for a MAC address to an individual port or a trunk.
Kingston Switch Configuration Utility 23 In this window, input the MAC address of a workstation, and choose an individual port or a trunk to which the workstation is connected. KNS3250/R Users Guide - Rev.
